With less than five days before the sales period closes, more than 2.5 million tickets have been sold for football's premier event. FIFA says the World Cup in Brazil is the most successful tournament in terms of ticket requests.

Most matches sold out quickly after tickets became available on March 12, but a few are proving tougher to sell.

Nigeria-Bosnia and Russia-South Korea, both in the wetlands city of Cuiaba, also have tickets still available.

Fans have until Tuesday to purchase tickets. The next sales phase opens on April 15.
